SMOKING-PIPE TESTER.

Application filed October 21, 1913.

tan, county and State of New York, have invented a new and Improved Smoking- Pipe Tester, of which the following is a full, clear. and exact description.

This invention relates to improvements in 2 testing devices, and particularly'to a smoking pipe testing device, andhas for an obj ect to provide an improved structure which effectually tests the action of the'pipe without necessitating placing the mouthpiece in the mouth.

Another object of the invention is to provide a testing device with a support for a smoking pipe and a pivotally mounted wind apparatus which is formed with a receiving member for the mouthpiece of the pipe, and with a collapsible bulb connected therewith through a suitable pipe or tube so that air may be drawn back and forth through the pipe when the same is in position.

In carrying out the object of the invention the same may be made in a large number of slightly different ways without departing from the spirit of the invention, provided means are formed which will force air' back and forth through the stem of the pipe. One form of the invention is to provide a suitable base and a support for the body of the pipe. Arranged adjacent this support is a second support which pivotally supports a wind device designed to draw in air and then expel the same so that when the pipe is arranged in position air will be drawn in .through the bowl and stem into the wind device and then expelled therefrom by reverse movement. This back and forth passage of air will indicate to the purchaser the condition of the draft of the pipe.

In the accompanying drawing the figure is a perspective view of a testing device embodying the invention.

Referring to the accompanying drawing by numeral 1 indicates a base which may be of any desired kind, to which is secured standards or uprights 2 and 3. The standard 2 is provided with a rounded or arcshaped pipe. supporting member 3, the same being formed integral with the standard 2 or rigidly secured thereto, as preferred. Standard 3 is provided with a bifurcated extension 4 for accommodating sleeve 5 which is Specification of Letters Patent.

provided with suitable journals 6 so that the sleeve 5 may be rocked back and forth. Mounted on the sleeve 5 is a tubular member 7 merging into a receiving end 8 for the mouthpiece of a pipe designed to be tested.

Tube 7 also merges into a bellowsor collapsible bulb 9 which may be formed of rubber or'other material which when collapsed will automatically expand as soon as air is allowedto enter therein. By collapsing and allowing air to expand bulb 9 air is drawn through members 7 and 8 and then expelled therethrough. If a pipe is in position, as shown in the dotted lines of the drawing, the air will be drawn through the bowl of the pipe and then the stem, and. then forced in a reverse direction through the same members. The receiving end 8 is preferably formed integral with tube 7, which tube is in turn preferably formed integral with bulb 9. The members 7, 8 and 9 may be placed in position in any desired manner in sleeve 5, as for instance by being compressed and forced therethrough or by spreading the sleeve 5, which sleeve is divided along line 10. After having spread the sleeve and placed the pneumatic device in place the sleeve is again compressed so as to form a substantially tight sleeve, as shown in the drawing, and. the device is ready for operation.

In use, a purchaser inspects a number of pipes and places the same in the testing device, as shown in the drawing. After the placing of any particular pipe in the testing device the bulb 9 is collapsed as often as desired. A new pipe-may be substituted at any time and tested, and so on until the pipe having the desired characteristics is found. This eliminates the purchaser contaminating the pipes by placing the same in his mouth, which is more or less objectionable.

Having thus described my invention I claim as new and desire to secure by Letters Patent, the following 2- 1. In a smoking pipe testing device, a base, a pair of standards arranged on said base, one of said standards having a pipe supporting member connected therewith, the other of said standards having a pneumatic 7 device pivotally mounted thereon, said pneumatic device extending toward said pipe supporting device and being formed with a tapering funnel shaped mouth for receiving the mouthpiece of a pipe resting on said 1 pipe supporting device whereby air may be forced through the stem and bowl of the pipe being tested.

2. In a smoking pipe testing-device, a pipe supporting structure and a pneumatic device associated with said pipe supporting structure, said pneumatic device comprising a head provided with a tapering funnel shaped mouth for receiving the mouthpiece of a pipe arranged in said pipe supporting device, a tubular connection, and a collapsible device for drawing in and expelling air, whereby air is forced in. opposite directions through the stem of the pipe being tested, said collapsible device automatically distending itself.
